STARTING APPARATUS FOR GASOLENE-ENGINES.

Specification of Letters I'atent.

Patented June 28, 1910.

Application filed March 9, 1910. Serial No. 548,147.

vide a device whereby the engine may be 7 started when cold without the necessity of hand-cranking the engine and without the addition thereto of any complicated machinery.

A further object is to enable my device to be applied to any of the usual types of engines as at present used for the above or other power uses.

. I attain these and other objects by the devices, mechanisms, and arrangements illustrated in the accompanying drawings, in which- Figure .1 is a section of a portion of a gasolene engine with my starting valve attached thereto, showing said valve in its normal or inoperative position; Fig. 2 is a similar section of the valve showing it in its intermediate position; Fig. 3 is a similar view showing the valve in its operative position; Fig. t is a detail of the valve-operating bar; and Fig. 5 is a general side elevation showing my apparatus as applied to the engine of an automobile.

Similar numerals of reference refer to similar parts throughout the several views.

Referring now to the drawings :The valve cap 1 screws into the cylinder casting 2 of the engine in the usual way, and is annular in form being screw-threaded on its inside to receive the plug holder 3. This consists of a casting screwed into the cap 1 and provided with a suitable screw-threaded hole to receive the spark plug 4 and with a valve casing 5 which may be either formed integral therewith or maybe rigidly secured thereto. A passage 6 extends from the inner end of the casting 3 to the valve chamber in the valve casing 5. An exhaust passage 7 is formed inthe valve casing 5 leading from the valve chamber therein through the casing. A gasolene passage 8 and a comp: .ssed-air passage 9 also lead into the'valve chamber at suitable positions therein as hereinafter described. A gasolene pipe 10 leads from the gasolene tank 11 to the passage 8. An air pipe 12 leads from the air tank 13 to the passage 9. A suitable air-pump 1% may be provided toreplenish the air in the tank 13 as it is used, though I propose that the tank shall be large enough to provide air for several startings of the engine without recharging, since the quantity of air used is very small.

The valve 15 which occupies the valve chamber in the casing 5 is provided with a gasolene receptacle 16 to which is connected the air passage 17 and also with an exhaust passage 18. The'positions of the passages in the valve 15 and through the casing 5 are such that when the valve is in its normal or inoperative position (Fig. l) the gasolene passage 8 is in connection with the gasolene receptacle 16 in the valve, and at the same time all other passages are closed; also when the valve is in the intermediate position (Fig. 2) the cylinder passage 6 is connected to the exhaust passage 7 through the exhaust passage 18 in the valve, and at the same time all other passages are closed; and when the valve is in its operative position (Fig. 3), the air passage 17 connects with the air passage 9 and the gasolene receptacle 16 connects with the cylinder passage 6, and all other passages are closed, whereby the gasolene is injected into the cylinder 9f the engine and is at thesamdtime vaporized and mixed with sufiicient air under pressure to make an explosive mixture of force enough to start the engine turning.

The valves 15 for all the cylinders of the engine are exactly alike and work together, each being provided with an arm 19, and all the arms. 19 being connected in corresponding positions to the valve operating bar 20. This bar 20 extends rearwardly to a convenient position and is provided with a handle or knob 21 at its end.

for the spring to engage the other end of the The bar 20 is held in the inoperative position by a spring secured thereto and to a suitable part 01" said slot. This point is chosen in such position thatthe spring 23 comes into action when the valve 15 is in the intermediate position described above and shown in Fig. 2. The efi'ect of this construction is to cause a momentary delay at this point suflici'ent to allow whatever compression may be confined in'the' cylinders 2 to escape through the exhau'st passage 7. On returning, however,

there will be no such,dela'y a'nd the springs" will turn the valve -so quickly as to make the exhaust action practically negligible. The action of myimproved starting apparatus may be. briefly described as follows 15-While the valves are in thenormalposition shown in Fig. 1,v the", receptacles 16 receive vmeasured gasolene from the receptacle 16 measuring passage t.

mg to the valve; a. compressed air supply a certain definite-z=.quant1ty of gasolene.

into the cylinder 2 and at the same time vaporizes it and mixes with it; The handle 21 1s then released and the valve 15 returns to its normal position under the action of the spr1ngs 22 and 23. Then, when the spark current 1s passed in the cylinder in which the piston is instarting position, the explosion in that cylinder produces suflicient force to turn the engine and then the subsequent ex-- plosions in the other cylinders add to the efi'ect and the engine is able to carry,- on its usual cycle.

Having described my invention what I claim is;

1. In an apparatus for startinggasolene eng nes, the combination with the engine; of a removable valve casing mounted thereon and having. a passage leading to the engine cylinder and an exhaust passage; a

valve in said casing and having a gasolene receptacle therein and an exhaust erein; a gasolene supply pipe leadpipe leading tothe valve; and means to oper- 5o ate said valve.

engines, the combination with the engine; of a removable valve casing mounted thereon and having a gasolene supply passage, a compressed air supply passage, an exhaust passage leading thereinto and a assage 2. In an apparatus for starting gasolene leading therefrom to the engine cylinder; a

valve-within the casing and having a gasolene measuring receptacle and anexhaust passage therein, said passages 'inthe casing and valve being arranged so that Whenthe valve is in inoperative position the gasolene supply passage 1s connected to the gasolene measuring receptacle and the other passages are closed, and when it is in its intermediate position the engine'passage is connected to the exhaust passage through the valve, and when it is in operative position the air supply passage :and the cylinder passages are connected to the ends of-the gasolene recep tacle, whereby a measured quantity of gasolene is injected in vaporized condition lnjtc the cylinder; and means'to'operate the active:'

whereby a pause is made at the intermediate position thereof. 1

3'. In an apparatus forstarting gasolene engines, the combination with the engine; of

a supply of gasolene; a supply of compressed a1r;,a valve controlling the supply of gasolene and compressed air and adapted to release the pressure in the engine cylinders and then to deliver a measured quantity of gasolene to the engine under the influence of the compressed air; a rod to operate said valve against the action of a spring; and asecond spring engaging the rod and in active during the first part-of its'motion whereby a pause in its motion is made to allow the released.

In testimony whereof I affix my signature in presence of two witnesses.
